WI T/VESSES TES CHRISTIAN WINTER, 0F OSKALOOSA. IOWA.
Specification of Letters Patent.
Application filed November 20, 1915. Serial No. 62,557.
To all whom it may concern Be it known that I, CHRISTIAN WINTER, a citizen of the United States, and a resident of Oskaloosa, in the county of Mahaska and State of Iowa, have invented a new and Improved Pole-Step, of which the following is a full, clear, and exact description.
This invention relates to steps and particularly to steps for transmission line poles or poles for any other purpose, and has for an object the provision of an improved arrangement whereby the step may be quickly applied and removed whenever desired.
Another object in view is to provide a pole and step which are formed so that part of the step may be removably fitted on to the pole in such a manner that the step will be held in a horizontal position.
A still further object in view is to provide an improved structure whereby part of a step may extend into a hollow pole or through the web of a pole and have certain parts of the step brace against the pole or the web so as to hold the step in a horizontal position.
In the accompanying drawing: Figure 1 is a side elevation of a step showing a hollow pole in connection therewith, the pole being shown in section; Fig. 2 is a horizontal section through Fig. 1 on line 22; Fig. 3 is a view similar to Fig. 2 but disclosing a slightly modified form of the invention.
Referring to the accompanying drawings by numerals, 1 indicates a tubular or hollow post which is used for supporting transmission lines or may be an ordinary telephone pole or pole for other use. However, in forming the pole 1 a number of apertures 2 are provided therein one above the other from near the bottom to near the top of the pole. These apertures are adapted to re-v ceive part of the step 3 so that the step may be properly supported as shown in Fig. 1. The step 3 is provided with a tread 4 having a turned-up end 5 so that the foot of an operator will not slip 011' the end of the step.
At the end adjacent the pole 1 the step is provided with enlargements 6 and 7, as shown more clearly in Fig. 2, while a restricted portion 8 extends through the apertures 2 and is bent so that the extreme contact end 9 will engage the inner face of pole 1. The bending of the section 8 may be so as to produce a perfect arc whereby the strain will be distributed throughout and the step 3 held properly in position at all times but also in condition for ready removal.
It will be noted that when a workman descends from the top of the pole 1 he may readily remove the steps and thereby prevent an unauthorized person from using the steps. It will also be noted that part of the step projects through the walls of the pole and presses against the interior face of the walls of the pole at a point above the tread l. The detail construction of the step is such as to adapt the same to tubular or hollow poles, as shown in Figs. 1 and 2 and also to adapt the step to poles formed with a web 10 as shown in Fig. 3.
The pole 11 shown in Fig. 3 is on the order of an I-beam and provided with a central web 10, which web is formed with apertures 2 through which section 8 projects as in the form shown in Fig. 1. It is of course evident that -a T-shaped pole or post could be provided with apertures, or in fact, other shapes so as to properly receive the section 9 and also so as to properly accommodate the enlarged fulcrum members 6 and 7.
What I claim is:
1. In a device of the character described, the combination with a pole having an aperture therein, of a step provided with a tread portion formed with enlargements adjacent one end, and a curved projection extending from said enlargement, said curved projection extending through said aperture and engaging part of the pole above the aperture whereby the enlargements may be used as fulcrums and the end of the curved portion as a bracing member.
2. A step for poles formed from a single piece of material and provided with a mem ber merging into a pair of laterally extending fulcrums, and an arc-shaped brace arranged at the end of the member carrying the fulcrums.
In testimony whereof I have signed my Patented'J an. 9, 1917.
